1. A surge protective device (SPD), comprising:
an overvoltage protection circuit; and
a control module coupled to the overvoltage protection circuit that is configured to monitor at least one performance characteristic of the overvoltage protection circuit and is further configured to communicate the at least one performance characteristic to a destination external to the surge protective device;
wherein the at least one performance characteristic of the overvoltage protection circuit comprises an impedance of a galvanic loop formed between one power line of a three-phase power line configuration originating at an electrical power transformer site and a neutral line or a protective earth terminal, the galvanic loop including the control module therein.
